ttdt_Revert(3)


CDE


NAME

  ttdt_Revert - request a ToolTalk client to revert a file


SYNOPSIS

  #include <tttk.h>
  Tt_status ttdt_Revert(Tt_message context,
			const char *pathname,
			Tt_scope the_scope,
			XtAppContext app2run,
			int ms_timeout);


DESCRIPTION

  The ttdt_Revert function sends a Revert request in the the_scope argument
  and waits for the reply. A Revert request asks the handling ToolTalk client
  to discard any changes pending on pathname.

  The context argument describes the environment to use. If context is not
  zero, messages created by ttdt_Revert inherit from context all contexts
  whose slotname begins with the characters ENV_.

  The the_scope argument identifies the scope of the request. If the_scope is
  TT_SCOPE_NONE, ttdt_Revert tries TT_BOTH, and falls back to
  TT_FILE_IN_SESSION if, for example, the ToolTalk database server is not
  installed on the file server that owns pathname.

  The ttdt_Revert function passes app2run and ms_timeout to
  tttk_block_while(3), blocking on the reply to the Save request it sends.


RETURN VALUE

  Upon successful completion, the ttdt_Revert function returns the status of
  the operation as one of the following Tt_status values:

  TT_OK
      The sent request received an affirmative reply within ms_timeout
      milliseconds.

  TT_DESKTOP_ETIMEDOUT
      No reply was received within ms_timeout milliseconds.

  TT_DESKTOP_EPROTO
      The request was failed, but the handler set the tt_message_status of
      the failure reply to TT_OK, instead of a specific error status.

  TT_ERR_DBAVAIL
      The ToolTalk service could not access the ToolTalk database needed for
      this operation.

  TT_ERR_DBEXIST
      The ToolTalk service could not access the specified ToolTalk database
      in the expected place.

  TT_ERR_NOMEM
      There is insufficient memory available to perform the function.

  TT_ERR_NOMP
      The ttsession(1) process is not running and the ToolTalk service cannot
      restart it.

  TT_ERR_OVERFLOW
      The ToolTalk service has more active messages than it can handle. (The
      maximum number of active messages is implementation specific, but is at
      least 2000.)

  TT_ERR_POINTER
      The pathname argument was NULL or was a ToolTalk error pointer.

  TT_ERR_PROCID
      The specified process identifier is out of date or invalid.
